The Gigapixel Camera #1 (GPC1) uses Orthogonal Transfer Arrays devices, a concept developed by Tonry et al. (1997). The detectors in GPC1 are CCID58 back-illuminated Orthogonal Transfer Arrays (OTAs), manufactured by Lincoln Labora- tory Tonry et al. (2008, 2006). They have a novel pixel structure with 4 parallel phases per pixel (Tonry et al. 2008) and required the development of a new type of controller, Onaka et al. (2008). GPC1 is actually populated with two different kinds of CCID58s, the CCID58a with a three phase serial register, and the CCID58b which has a two phase serial register (Onaka et al. 2012). For the science data discussed in the Pan-STARRS1 papers and presented in the public data release, the devices were always operated without OT and in a normal readout mode, and none of public Pan-STARRS1 data has OT correction.
The detectors are read out using a StarGrasp CCD
controller, with a readout time of 8 seconds for a full
unbinned image. Performance assessments are presented
in Tonry et al. (2008); Onaka et al. (2012)
